2、bundle:  Etymologically, bundle is ‘that which binds or is bound’. Like band, bend, bind, and bond, it can be traced back ultimately to an Indo-European base *bhendh- ‘tie’. The Germanic base *bund-, derived from this, produced Old English byndelle ‘binding’. There is no direct evidence to link this with the much later bundle, although the similarities are striking. Alternatively, the source may be the related Middle Dutch bundel ‘collection of things tied together’.=> band, bend, bind, bond
4、early 14c., "bound collection of things," from Middle Dutch bondel, diminutive of bond, from binden "to bind," or perhaps a merger of this word and Old English byndele "binding," from Proto-Germanic *bundilin (source also of German bündel "to bundle"), from PIE root *bhendh- "tie" (see bend (v.)). Meaning "a lot of money" is from 1899. To be a bundle of nerves "very anxious" is from 1938.
6、1620s, "to make into a bundle," from bundle (n.); meaning "to wrap up in warm heavy clothes" is from 1893. Meaning "to sleep with another, clothed, in the same bed," a noted former custom in New England, is from 1781. Meaning "to send away hurriedly" is from 1823. Related: Bundled; bundling.
